Since the body is a physical object, subject to physical laws, it follows that at least the connection between the two (body and soul) must obey the laws of physics.
Another question is what is the currency used by the two in their communication. Physical forces are mediated by subatomic particles. What serves to mediate between body and soul?
Language could be the medium and the mediating currency. It has both an internal, psychic representation and an objective, external one. It serves as a bridge between our inner emotions and cognition and the outside, physical world. It originates almost non-physically (a mere thought) and has profound physical impacts and effects. It has quantum aspects combined with classical determinism.
We propose that what we call the Subconscious and the Pre-Conscious (Threshold of Consciousness) are but Fields of Potentials organized in Lattices.
